  2. Pressure swing adsorption - Wikipedia

    en.wikipedia.org/wiki/Pressure_swing_adsorption

    PSA is also used in: Hypoxic air fire prevention systems to produce air with a low oxygen content. On purpose propylene plants via propane dehydrogenation. They consist of a selective medium for the preferred adsorption of methane and ethane over hydrogen. [2] Industrial nitrogen generator units based on the PSA process can produce high-purity ...

  3. Nitrogen generator - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_generator

    High nitrogen purity: PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide – up to 99.9995% nitrogen. But in most cases they do not produce more than 98.8% nitrogen with the remainder being argon that is not separated from the nitrogen by the usual PSA process.

  4. Air separation - Wikipedia

    en.wikipedia.org/wiki/Air_separation

    A nitrogen generator Bottle of 4Å molecular sieves. Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.

  5. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    Oxygen concentrators using pressure swing adsorption (PSA) technology are used widely for oxygen provision in healthcare applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or portable clinics. For other purposes, there are also concentrators based on nitrogen separation membrane ...

  6. Nitrogen rejection unit - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_Rejection_Unit

    For smaller volumes of gas, a system utilizing pressure swing adsorption (PSA) is a more typical method of separation. In PSA, methane and nitrogen can be separated by using an adsorbent with an aperture size very close to the molecular diameter of the larger species, in this case methane (3.8 angstroms). This means nitrogen is able to diffuse ...

  7. Gas separation - Wikipedia

    en.wikipedia.org/wiki/Gas_separation

    Gas separation can refer to any of a number of techniques used to separate gases, either to give multiple products or to purify a single product. Swing adsorption techniques [ edit ]

  8. Portsmouth Gaseous Diffusion Plant - Wikipedia

    en.wikipedia.org/wiki/Portsmouth_Gaseous...

    Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio, that previously produced enriched uranium, including highly enriched weapons-grade uranium, for the United States Atomic Energy Commission (AEC), the U.S. nuclear weapons program and Navy nuclear propulsion; in later years, it produced low-enriched uranium for fuel for ...
